Fpsa/tpsa ratio

Free/total PSA ratio is a powerful predictor of future prostate cancer morbidity in men with initial PSA levels of 4.1 to 10.0 ng/mL. Men with PSA levels of 4.1 to 10 ng/mL who are not suspected of having prostate cancer by whatever means should undergo %fPSA measurement and be carefully monitored at short intervals over the long-term if they have. The free/total prostate-specific antigen ratio (%fPSA) is the best predictor of tumor involvement in the radical prostatectomy specimen among men with an elevated PSA Urol Oncol . Sep-Oct 2002;7(5):195-8. doi: 10.1016/s1078-1439(02)00190-4 The measure of free PSA percentage serves a similar purposeto indicate whether a biopsy is warranted. Total PSA is made up of two sub-types: free and bound (or complexed) PSA . PSA gets bound to proteins when PC is present. Therefore, a low free PSA percentage suggests malignancy

The free PSA concentration is divided by the total PSA to derive the free:total ratio. The PSA, total and free test provides a free PSA measurement on every specimen, however, because very high or low total PSA measurements are predictive in themselves, a ratio is provided only when the total PSA is in the range of 4.0 to 10.0 ng/mL. PDF Report N Ratio of free PSA to total PSA is 13.5℅ with a free PSA of 1.45. I Have had one biopsy operation about 1 year ago, Needle biopsy of prostate with diagnosis of benign prostatic tissue and no cancer. 40*47*61 mm are dimensions of prostate and regular size.Weak urine flow on occasion and occasional problems emptying bladder Beide zusammen werden als Gesamt-PSA (totales PSA oder tPSA) gemessen. fPSA, isoliert betrachtet, enthält keine bedeutsame Aussage, es gilt als biologisch inaktiv. Die Bestimmung des prozentualen Anteils des freien PSAs am Gesamt-PSA erlaubt eine deutlich verbesserte Spezifität bei der Unterscheidung zwischen gutartiger Prostatavergrößerung bzw Desidererei conoscere il mio, i cui valori sono: psa 2.00 fpsa 0,67. Buongiorno. È una semplice divisione tra il libero ed il totale il risultato se è superiore a 20 è buono ovviamente va.

Diagnostic validity of tPSA, cPSA, and the fPSA/ tPSA

Dieser Wert heißt auch total PSA oder abgekürzt tPSA. PSA-Werte - was der PSA-Quotient besagt. Beim Verdacht auf Prostatakrebs errechnen Ärzte nicht nur das freie PSA und das Gesamt-PSA, sondern auch den sogenannten PSA-Quotient. Dieser Wert ist das Verhältnis von freiem PSA zum Gesamt-PSA, also fPSA/Gesamt-PSA Prosečan PSAD indeks kod ljudi sa normalnom prostatom iznosi 0,090, kod ljudi sa povećanom prostatom ili upalom prostate 0,099 i kod ljudi sa rakom prostate iznosi 1,73. U preciznijoj dijagnostici, koristi se i tzv. PSAV, tj. promena vrednosti PSA u određenom vremenu. Ukoliko je povišenje PSA veće od 0,75 mg/ml za godinu dana, onda je to. 3,5 - 20 ng/ml, hodnoty fPSA 0,19 - 4,89 ng/ml a poměr f/t PSA 0,035 - 0,57. Přehled obou sledovaných skupin v závislosti na hod-notách poměru f/t PSA a PSA nám ukazuje graf č. 1.

Medián poměru f/t PS Comparing the results of total and free PSA tests can give doctors an idea of how likely it is that a person has prostate cancer. Free PSA ranges can vary, but generally, a higher ratio of free PSA..

strated that the fPSA/tPSA ratio (the percent free PSA [%fPSA]) results in a significant enhancement in spec-ificity.4-9 Among patients with elevated tPSA, men with benign prostate hyperplasia (BPH) tend to have higher %fPSA ranges than men with PCa.10 Despite these encouraging results, several prob-lems remain with regard to the %fPSA. It has been confirmed that %fPSA increases with older age9 an Quando il PSA totale è compreso tra 4 e 10: un ratio libero/totale inferiore od uguale al 10% indica che è piuttosto elevata la possibilità di tumore alla prostata (dal 49% al 65% dei casi), un ratio superiore al 25% indica un rischio di cancro molto più basso che varia anche in base all'età (età più elevate hanno un rischio maggiore) Valori normali. Il valore-limite di PSA totale oltre al quale si rendono necessari accertamenti è solitamente 4 mg/dL. Nel caso in cui si riscontri un valore di PSA elevato (quindi superiore a 4 mg/dl) può risultare dirimente studiare il PSA ratio; in particolare, in tabella è riportata la correlazione tra età e PSA ratio in termini di. Many investigators have demonstrated that the fPSA/tPSA ratio (the percent free PSA [%fPSA]) results in a significant enhancement in specificity. 4 - 9 Among patients with elevated tPSA, men with benign prostate hyperplasia (BPH) tend to have higher %fPSA ranges than men with PCa. 1 Quando si parla di PSA libero (talvolta indicato come free PSA o fPSA) si fa riferimento a una frazione della quantità totale di PSA circolante nel sangue; il PSA (Prostate-Specific Antigen, antigene prostatico specifico) è un enzima prodotto dalla prostata le cui principali funzioni sono quelle di ritardare la coagulazione e l'essiccamento del liquido seminale dopo l'immissione di questo all'esterno

PSA totale - PSA libero - ratio (% PSA lib/tot) Il PSA (antigene prostatico specifico) è una proteina prodotta dalla prostata. Si misura il dosaggio nel sangue perché un suo aumento può indicare la presenza di un tumore prostatico. Non è un esame specifico: il riscontro di elevati valori non è sufficiente a formulare la diagnosi di tumore, poiché. diagnostische Grauzone bezeichnet wird, ist der prozentuale fPSA-Wert (fPSA/tPSA x 100) besonders nützlich. Je geringer der prozentuale fPSA-Wert, desto höher ist das Risiko eines Prostatakarzinoms. Die Wahrscheinlichkeit dafür, in der Biopsie ein Prostatakarzinom nachzuweisen, ist nachfolgend nach Alter und prozentualem fPSA-Wert dargestellt

Free/total PSA ratio is a powerful predictor of future

When total PSA concentration is above 10.0 ng/mL, the probability of cancer is high and prostate biopsy is generally recommended. The total PSA range of 4.0 to 10.0 ng/mL has been described as a diagnostic gray zone, in which the free:total PSA ratio helps to determine the relative risk of prostate cancer (see table below) Dal rapporto tra questi due valori, ovvero tra PSA libero e PSA legato, otteniamo il PSA ratio, mentre dalla somma degli stessi si ricava il PSA totale. Se ad essere elevato è il PSA libero, solitamente la diagnosi che ne deriva contempla condizioni benigne, quali l'ipertrofia prostatica benigna

The median tPSA levels for patients with prostate cancer and benign histological findings were 10.1 ng/mL (95% CI: 7.3-13.9) and 1.3 ng/mL (95% CI: 1.2-1.3), respectively (p < 0.0001). f/t PSA ratio had an AUC value of 0.81 (95% CI: 0.80-0.82) for all age groups in detecting prostate cancer. f/t PSA ratio of 10% had a specificity of 95% (95% CI: 94-95) with a PLR of 7.6, and f/t PSA ratio of 30% had a sensitivity of 91.7% (95% CI: 85-96) with a NLR of 0.23 in all age groups Abstract. Background: The ratio of free PSA in total PSA (f/t) has been reported to improve the diagnostic accuracy of prostate cancer in the group with slightly elevated serum PSA values. In Japanese cases, the clinical significance of f/t is still controversial. Methods: The diagnostic significance of f/t in serum for prostate cancer was evaluated in a cooperative study The median cPSA/tPSA, fPSA/tPSA, and fPSA/cPSA ratios were significantly different between patients with BPH and PCa (78.7% vs 90.7%, 25.5% vs 12.1%, and 36.8% vs 14.3%, respectively; P <0.001. The reference limits in different age groups (21-50, 51-60, 61-70, 71-80, and ≥81 years) were 2.07, 3.59, 4.93, 6.83, and 7.73 ng/mL for tPSA, and 0.60, 0.76, 0.83, 1.30, and 2.41 ng/mL for fPSA. The RIs of %fPSA were ≥0.16 for 21-50 years and ≥0.13 for male over 50 years old

The fPSA/tPSA ratio allowed the discrimination of PCa from BPH with satisfactory sensitivity and specificity when considering patients less than 60 years of age (100% and 95%, respectively). PSA and PSM mRNA were positive in 1 and 7 of 13 EPD samples, 6 and 13 of 25 PCa samples, and 6 and 17 of 38 BPH samples.. The ratio fPSA/tPSA has been demonstrated to improve the sensitivity and specificityin patients with tPSA values in the gray zone of 4.00 10.0 ng/mL. An equimolar tPSA determination is the prerequisite for reliable ratios. In patients receiving therapy, particularly hormone withdrawal therapy, th

To evaluate the value of free PSA/total PSA ratio (fPSA/tPSA) to boost total PSA (tPSA) specificity in the diagnosis of prostate cancer in a series of symptomatic patients. Material And Method Prospective study on 334 patients presenting symptoms compatible with PBH and tPSA (ProStatusTM, Wallace Oy, Turku, Finland) between 2.5 and 20 ng/ml. PSA se koristi i kao tumorski marker za oboljenja prostate i ako nije dovoljno osetljiv tumorski marker, jer može biti povišen i kod benignih i kod malignih oboljenja prostate. Takođe, određen broj pacijenata sa karcinomom prostate uopšte nema povišene vrednosti PSA u krvi. I pored ovih nedostatka, PSA test je za sada najbolji tumorski. The ratio fPSA/tPSA has been demonstrated to improve the sensitivity and specificity in patients with tPSA values in the gray zone of 4-10 ng/ml. An equimolar tPSA determination is the prerequisite for reliable ratios. In patients receiving therapy, particularly hormone withdrawal therapy, the fPSA/tPSA ratio cannot be utilized to. fpsa/tpsa >0.16. 前列腺穿刺阳性率为11.6%. fpsa/tpsa <0.16. 前列腺穿刺阳性率为17.4%. 因此国内推荐fpsa/tpsa>0.16 为正常参考值(或临界值)。 总结一下,tpsa就是血液中的总psa含量,包括和血液蛋白结合的psa,以及没有结合的游离psa,也就是fpsa - PSA free/total PSA ratio. The test is performed in men whose total PSA level is within: 4-10 ng/ml (the so-called grey diagnostic zone) to differentiate between benign prostatic hyperplasia and prostate cancer. The test calculates the percentage of free PSA by comparison with the total PSA concentration (fPSA/tPSA x 100)

About FPSA. The Food Processing Suppliers Association (FPSA) is the trade association for suppliers to the food processing and packaging industry and the host of the largest and most affordable food processing trade show in the Americas. Our goal is to provide members with networking, marketing and educational opportunities and to help assure. Objective To compare the ratio of free prostate specific antigen (fPSA), total PSA (tPSA) and complexed PSA (cPSA, measured using a novel immunoassay) with other variables used to detect prostate cancer in patients with intermediate serum PSA levels of 4.1-10.0 ng/mL.. Patients and methods . From July 1997 to August 1998, 140 consecutive patients were assessed; all had intermediate serum PSA. In our meta-analysis, the cutoff values for f/tPSA ratio of the included studies varied and were usually between 0.14 and 0.25. As there are no international standards of cutoff value right now, most studies included in our meta-analysis did not describe the immunometric assay, which is used for the detection of serum PSA and fPSA levels, and. Ai fini di una corretta valutazione clinica è indispensabile valutare il rapporto (ratio) tra il free-PSA ed il PSA Totale. Cosa significa questo rapporto? Il rapporto va considerato dubbio se i valori sono compresi tra 10 e 20 e quindi necessita di ulteriori accertamenti, patologico se il valore è minore di 10 (sospetto carcinoma prostatico.

The calculated ratios fPSA/tPSA, PSA-ACT/tPSA and cPSA/tPSA were not significantly different. CONCLUSION: The determination of PSA-ACT or cPSA and the associated ratios do not improve the diagnostic impact to discriminate between PCa and BPH compared to fPSA/tPSA ratio. The ratios PSA-ACT/tPSA or cPSA/tPSA can be considered to be alternative. Percent free PSA (%fPSA), free-to-total PSA ratio (fPSA/tPSA) testing and/or complexed PSA (cPSA) testing is considered medically necessary for determining the need for prostate biopsy in a man with a normal or equivocal digital rectal examination (DRE) and an elevated tPSA of 4 -10 ng/mL

The AUC values indicated enhanced performance of IGF-I/fPSA ratio (AUC = 0.753) in PCa detection compared with the currently used f/tPSA (AUC = 0.689). Multivariate logistic regression confirmed the observed relationships and identified IGF-I/fPSA as independent factor in PCa presence Men without prostate cancer generally have a higher ratio of fPSA to tPSA compared to men with prostate cancer. With mild elevations of tPSA, fPSA analysis may aid in distinguishing between benign and malignant conditions of the prostate. Recent research has shown that adding fPSA to prostate cancer screening could identify 52% of the high-risk. cPSA ist deutlich besser lagerungsstabil und deutlich weniger empfindlich gegenüber Prostatamanipulationen als tPSA oder fPSA. cPSA bietet wegen der direkten Messung des mit Tumorwachstum assoziierten komplexierten PSA-Anteils Vorteile in der frühen Diagnostik von PCa, insbesondere bei Patienten mit einem tPSA < 4,0 ng/ml (tPSA), free serum PSA (fPSA) and the ratio of free-to-total prostate specific antigen (%fPSA). The role of free and %fPSA as a diagnostic tool for distinguishing between cancer and non-malignant diseases of the prostate was also investigated. Material and Methods: In a retrospective study 1090 prostate biopsies performed between January 2000 an Serum fPSA and ratio of fPSA/tPSA were similar amongst the three groups. It is well established that fPSA/ tPSA ratio is useful when the total PSA level is between 4-10 ng/ml. Since in our study the tPSA in all patients and control subjects is below 4 ng/ml, the fPSA/tPSA ratio does not alter in hepatic dysfunction
